2 SHEETS-SHEET 2- its wedging surfaces in engagement with the corresponding surfaces of the/.telly band,

these means being shown as comprising a bolt 8 upon which screws a nut 9 carrying a keeper 10.

ln order to insure a satisfactory engagei y of their analogy to the lands or high portions' inthe bore, ot' a riled gun. In the` form of my invention shown in Figs. 1, 2

and 3,. these lands, designated-by thefnu'- meral 11, are formed upon the inclinedfsu'rfaces and 4 of the felly band,the lands on the two surfaces being arranged in staggered relation. Any smtable number ot these lands may be provided; for instance,

for a thirty-four inch wheel, twelve or sixteen upon each inclined surface would be satisfactory. The lands are preferably ma de quite low I; for instance', I find that a height of one-thirty-second oi an inch is fptlicient.

I do not wish to limit myself either 'as to the number of lands to be provided or as to ,their height by the figures given. v'The lands may be much higher, or in some 'cases lower than the dimensions mentioned, and may be manyor few, as maybe found satisfactory by the constructor. V'Ihe function 'oi' these lands is to provide the primary bearing sur- 'face for the tire-carrying rim, and to make allowance for inequalities inthe ydimensions 40 of the latter. F or eXample,-if a particular tire-carrying rim is yslightly larger in diameter /than the standard (within certain permissible limits. of course), it can be seated `v`upon the lands'fvl/land forcedlaterally into v the desired predetermined lposition which it should* occupy.; vthat is,"whilejretaining a strictly circulalconliguration. 'If a rim of f uponthe same felly'band, it could also be 6.0 circumference, but the saine result .is accom,-

. run may in some casesv result in .the same engaging l,the surfaces and, e'. of the telly lands, as they may be called by reason forced fullyupon the same andlatera'fl'ly to ously de scribed. plished by the.. use of the spaced projections resulting in the slight distortion of the rim, as above described. This distortion of the' band between the lands, but thisl is not ob-' gectionable, nor does it always occur. Such 'engagement serves to provide additional points of support for the rim. In fact,

where the rim does not engagerbetween the rlands simply by the forcing of the same upon the felly band, vsuch.engagement may 'i occur at the bottom of the wheel, where the .same rests upon the ground. This mayitake however, not necessaryv if 'the ladsare 80 placed sufficiently close together.,

With the lands arranged in staggered relation, as shown in Figs. l and 2, a slight twisting of the rim in alternate directionswill take' place,'by which `the full benefit of the rim is made use of and-rims at considerable variations in dimensions can' be satisactorily accommodated- Y c In Fig.' 5 I have shown how lthe landsill upon the telly band may be arrangedoppO- site to eachother upon the two inclined survfaces Bland 4'. @ther arrangements of lthe lands upon the folly band will suggest themi selves.

lfVhile, as I have stated,the lands may'be 95 made of any desired height, it is highly desirable, and I prefer in all cases to make them only of such height that the tireecarrying rimif depressed between them into c'on-x tact with the surface fromnvhich they lproject, will. not be distorted beyondits elastic limit. The stresses to which a rim is subjected in use are frequently suiicient materially to deform a rim of ordinary dimen"` sions, unless the saine isthorougxhly supported, but by limiting the -heig t of the lands,'it will be seen that before ingury can .occurthe rim will seat 'itself solidlyton `the bearing surfaces .of the wheel between fthe lands and further deforn'atin will bepre- 110 vented. The danger of permanent' distor.v

.'tion ofthe rim is thusefectually eliminated.
